y s claims. (ci.A sis-19s), My invention relates to the treatment of fine i" operations to which rayon is necessarily subjected, before the precipitated and package-collected thread can'be considered a final product ready for the market, such treatments including variouswater washings. desulphurizing, bleaching, oiiing, sizing, dyeing, drying, and other purifying and finishing operations. The particular objects of the invention are to provide economical and reliable apparatus for effecting these fluid treatments, apparatus whichwill function without -cliscoloring o r otherwise 'contaminating the thread, and which will permit suitable loosening up of the freshly-spun packages by the fluid treatment so as to provide for all parts of the package their respective scopes of natural free play, relative to other parts of the package;v without injuriously disarranging the thread or e mump e mamen onwhch th? thread is i the same parts are indlcated bythe same respeccomprised. The annexed drawings and the following description set forth in detail certain means illustrating my improved apparatus, such means constituting, however, only a few ofthe various forms in whchthe principle of the vimproved apparatusmay be embodied. j y In said annexed drawings: U y. z

lFigure 10 is a fragmentary vertical section, upon an enlarged scale, illustrating the method for securing to an insert an outwardly-extended fiange' forming a package support and also serv- 20 ing as a separator between the contiguous ends of vertically-adjacent packages of a tier.

Referring to the'annexed drawings, in which tive numbers in the several views, my improved 25 apparatus includes a plurality of tubularfrustoconical axially-aligned columns forming package inserts I and each having secured thereto, and adjacent one end thereof, an ou` ardly-extended ange 2 forming a package sup rt. These pack- 3o age supports 2 also serve as spacers betweeh vertically-adjacent packages. This package support 2 is formed with an up-turned peripheral edge 3. Upon the flange 2 a frusta-conical tubui lar rayon package 4 is mounted, being retained 35 in position thereon by the up-turned edge 3, the E diameter of the inner face of the package 4 being materially greater than that ofthe outer surface of the insert I so'that an annular space ll is l'provided between the outerface of the insert l v40 and the inner face of the package 4, in which )space Il the tubular package 4, under the fluid treatment,k may expand inwardly and become loosened and hence more porous, as illustrated by the treated packages shown in Figure 3. By means hereinafter fully described, a plurality of the insertsl are formed Vinto an axiallyaligned vertical tier ,of communicating insertsf, and Athe tier mounted upon a soft rubberseat 5 having a port-9 therethrough .formed with`. en- 5o' larged outer end portions 91 and V92 servingpto receive iiuid from comparatively large areas. The soft rubber seat E isin turn mounted upon and secured in a main base 'i4 through which treating uid passes to and from the central chamber 5g y22 formed by thetier of communicatinginserts I, the port 9 communicating with a port I4 formed in the top of the main base I4.

It will be understood that there are treated in any one operation any suitable'number of suitably spaced andJarranged tiers of rayon packages, of which one tier only is shown for'fillustration in Figure 1.

'Ihe inserts I are each provided with a multiplicity of ports 8. Therefore, it is evident, that-treating uid can be passed from the base I4 through the ports I4 and 9 into the central chamber 22 formed by the communicating inserts and thence outwardly through the ports Il into the spacesI I whence it passes through the rayon packages 4. Likwise, treating fluid can be passed fromwithout the packages 4 through the same and into the space II and thence through the ports 8 and the l central chamber 22 and the ports 9 and I4' and outwardly through the base I4. This fluid treatment is effected in a suitable treatment tank I3, which also is mounted upon the base I4 and secured thereto by a peripheral angle |32 which is welded to the bottom of the sides of the tank I3. Any suitable number of laterally-spaced tiers of inserts I and supported packages 4 may be mounted in the tank I3 upon the base I4 and the inserts of the several tiers are locked together into compact formations by a suitable plate 6' mounted upon a peripheral rubber pad 'I superimposed upon a peripheral angle I3 rwelded to theside of and adjacent the top .of the tank I 3, the plate 5 being actuatedby any suitable clamping means 23.

By means of communicating ports (not shown) in the bottom of the tank I3 and in the top of the base I4, the treating fluid canbe passed from the space 24 in the tank I3, between and around the several package tiers: i. e., the space in the tank I 3 outside of the packages 4, outwardly of the tank I3, or passed into the space 24 through suchports, dependent upon the direction of flow of the treating fluid, whence it passes to the source of supply through the base I4, or passes through the bodies of the packages. 4 into the spaces II. ports and means for reversing liquid flow are well known and a showing thereof is not required for an adequate understanding of the instant invention. An overflow lip for the treating fluid from the tank I3 intermediate the tiers of inserts is indicated in Figure 1.

In ord r to insure that the topmost packages of the tiev of packages shall be adequately covered with the treating iiuid,l I provide an extended top insert forming a suitable cap member yIII for each tier of inserts I, the same being com.-

pletely closed except that it is open at its bottom end which is 4of a formation similar to that' of the bottom of an insert I. This cap member I0 is of cylindrical formation having a crosssection equal to that of the larger end of an insert I and is supported upon the topmost insert I of the tier and communicates through its open bottom therewith. l

I provide improved means for supporting the cap member I0 upon the tier of inserts, for mounting the inserts I one upon the other, and

for securing the package-supporting and sepaf rating anges 2 to the inserts I. The insert and cap supports are formed by punching inwardly the material of the bodies of the inserts and the cap somewhat inwardly of one end thereof, the largeI end in the case of the inserts I, so as to form a horizontal series of spaced tonguesy I l, as.

'I'his structure of tank and base upon the top of the insertadjacently below, the l frusta-conical formation of the insert I permitting the smallerend thereof to be inserted into the larger end of the insert 'adjacently above, or into the cap member I0, as clearly shown in the accompanying drawings and particularly in Figures 8 and 9.

The inserts I and 'supporting flanges 2 and cap member I0 are formed of stainless steel. I secure the inserts I and the cap member I0 to the flanges 2 by the improved means now to be described. The same means also apply to the securing of a cover member I0' to the top of the cap member Iil, as shown in Figure 7. The inserts I and c'ap members I0 are formed with horizontal seriesof holes I5 therethrough adjacent one end of each of the inserts I and adjacent both ends of the capmember I0. An upturned inner edge I6 of a ange 2 is forced over the larger end of an insert Il or one end .of the cap member I@ and material I 'I of the edge I6 punched into the holes I5 formed in the insert I and cap member IIJ, as clearly shown in Figure 10. The cover member III is secured to the top of the cap member I 0 in like manner, Figure 7, by means of' a downwardly-extended flange |02, holes I5, and-material I 03. It will be noted that the terminal portion 2l of the inner edge I6 of the topmost flange or separating member 2 is crimped inwardly against the body of the tongues It, Figure 8, in order more securely to mount and center the cap member I0 and to render this joint substantially water-proof.

I direct particular attention to the fact that the supportingand separating flanges 2 are vertically spaced aparta distance somewhat greater than the height of one of the untreated packages- 4, thus leaving a slight space I9, Figure 1, be-

"'ly increase its outer diameter during the iiuld y treatment; in fact, it becomes Vsomewhat smaller in outer diameter, as indicated by the spaces 20, Figure 3, between the outer faces of the treated packages 4 and the upturned flange edges 3, which spaces 20 ,are relatively larger than vthe corresponding spaces in Figure 1. 'I'he increase in thickness in the body of the packages takes,k

place inwardly so that the packages when the fluid treatment is completed practically ll the spaces II, but they do notrtightly engage the outer faces of the inserts I, as is indicated by the resultant final small space I2, Figure 3, due to which and the conical structure of the inserts it is possible easily to remove the treated packages from the inserts I.

As stated, the inserts I, flanges 2, and cap members I0 are made of stainless steeland, in order. that the other parts of the apparatus may be rendered non-corrosive, the exposed surfaces of the tank I3 and angles I3' and I 32 are provided with rubber liners; as also, the bottom face of the locking member 6 and the exposed surfaces of the base I4, all as clearly shown in Figure 1.

What I claim is:

1. A package insert for treating a tubular package of thread ofi-lne filamentous character' column having package-supporting means, and spaced inwardly-projected insert-supporting tongues formed from the b'ody of the column adjacent the `larger end of the latter and serving also to nest the insert with another like insert.

2. In apparatus for treating tubular packages of thread of rie lamentous character, a ported tubular column having 4package-supporting means, and acap member having package-spacing means adjacent its lower end, said cap member also having a bottomopening communicating with the chamber of the column, the cap member being formed with spaced inwardly-projected tongues adjacent its open end by which it is supported upon one end of the column.

V3. In apparatus for treating tubular packages of thread o! tine filamentous character, a ported tubular column having package-supporting means, and a cap member having a bottom opening communicating with the chamber of the column,` the cap member being formed with spaced inwardly-projected tongues adjacent its open end by 'which it is supported upon one end4 of the co1umn,vthe cap member also having a transverse series of spaced holes therethrough and a laterally-projected package-spacing ange having an upturned edge portion secured to the cap member by materialthereof `forced into the series of holes, the terminal of the upturned edge portion being crimped against the tongues.
